1.5 The Theory of Plate Tectonics


Vocabulary

Plates:Separate sections broken by the lithosphere
Scientific Theory: A well tasted concept that explains a wide range of observation
Plate Tectonics: A geological theory that states that pieces of earth's lithosphere are in constant, show motion,driven by the convection currents in the mantle
Faults: breaks in earth's crust where rocks have slipped past each other
Transform boundary: a place where two plates slip past each other, moving in opposite direction
Divergent Boundary: When two plates split or diverge
Rift Valley: forms along the divergent boundary
Convergent Boundary: the place where two plates come together, or converge
